큰실말(Cladosiphon novae-caledoniae kylin, C. novae-caledoniae kylin) 부산물을 이용하여 화장 품 소재로써 가능성을 조사하고자, 항산화 효과(DPPH 자유 라디칼 소거 활성), 항균(anti-microbial activity), 미백(tyrosinase inhibition assay), 주름개선(elastase inhibition assay) 및 B16F10 mouse melanoma cell (MTT assay)을 이용한 세포 생존률을 측정하였다. 큰실말 추출물 원물(MC)과 불용성(MI)은 Staphyloccus aureus (S. aureus)와 항생제내성균주인 MRSA에 대하여 활성을 나타내었지만 항곰팡이 활성은 나타내지 않 았다. 큰실말 추출물 수용성(MS)은 tyrosine에 대한 tyrosinase 저해효과가 49%로 표준물질인 arbutin 보다 미백효과가 우수하였지만 주름개선효과는 비교적 낮은 활성을 나타내었다. DPPH 라디칼 소거능력은 500 μ g/mL에서 89%로 나타내었다. 따라서 본 연구인 큰실말 추출물은 화장품 미백소재로써 좋은 후보군임을 확인 할 수 있었다.
To investigate the effect of dietary fiber from mozuku, Cladosiphon novae-caledoniae kylin (C. novae-caledoniae kylin) on the skin care, we measured anti-oxidant activity, anti-microbial activities, tyrosinase activity inhibition and elastic activity. B16F10 melanoma cell (MTT assay) were used to measure cell viability. MC and MI exhibited in vitro antibacterial activity against Staphyloccus aureus (S. aureus) and MRSA without antifungal activity. Mozuku extract (MS) showed excellent tyrosinase inhibition effect compared to arbutin as a positive control (to 49% for tyrosine). The wrinkle-improving effect was relatively low. However, wrinkle-improving effect was relatively low. DPPH free radical scavenging activity was 89% in a concentrations at 500 μg/mL. These results indicate that the mozuku extracts may be an effective cosmetic ingredient for skin whitening.
